Inspect the condition and connections of all cooling system and heater hoses. Replace any that are swollen or deteriorated. The coolant should be at full in the radiator and between the FULL and LOW marks on the coolant reservoir when the engine is cool. CAUTION Ø Radiator coolant will damage paint. Rinse it off quickly if spilled. Ø Use only soft (demineralized) water in the coolant mixture. Water that contains minerals will cut down on the coolant's effectiveness. Ø Don't add only water. Always add a proper coolant mixture. Ø The engine has aluminum parts and must be protected by an ethylene-glycol-based coolant to prevent corrosion and freezing. Ø DO NOT USE coolants Containing Alcohol, methanol, Borate or Silicate. These coolants could damage the cooling system. Ø DO NOT MIX alcohol or methanol with the coolant. This could damage the cooling system. Ø Don't use a solution that contains more than 60% antifreeze. This would reduce effectiveness. If it's at or near LOW, add enough coolant to the coolant reservoir to provide freezing and corrosion protection and to bring the level to FULL. 8-23 Form No.8AS7-EA-09E
